DETAILED DESCRIPTION OF THE EMBODIMENT

Referring to FIGS. 13, the present invention provides an electrical connecting interface of mobile data storage device for electrical connecting a host system with a data storage unit. The host system is a personal computer, industrial server, or any other electric appliances. The mobile data storage device can be a mobile hard disk drive, a floppy disk drive, an optical disk drive etc. The electrical connecting interface comprises a first electrical connector 10 mounted inside a holder frame 30, and a second electrical connector 20 disposed on a data storage device 60. By means of connecting the first electrical connector 10 to the second electrical connector 20, the host system and the data storage device 60 directly electrically connect with each other to transmit data and power without any other interface requirement.

The aforesaid first electrical connector 10 and second electrical connector 20 are SATA (Serial Advanced Technology Attachment) type electrical connectors. The first electrical connector 10 comprises a first connecting terminal 17 for transmitting data, a second connecting terminal 18 for supplying power, a signal cable 13 extending from the internal circuit (not shown) of the host system and connected to the first connecting terminal 17, and a power cable 14 extending from the power circuit of the host system and connected to the second connecting terminal 18. The second electrical connector 20 comprises a first corresponding connecting terminal 21 and a second corresponding connecting terminal 22. The signal cable 13 and the power cable 14 are respectively electrically connected to the first connecting terminal 17 for transmitting data and the second connecting terminal 18 for supplying power with contact terminals 15.

Referring to FIG. 1 and FIG. 4, the first electrical connector 10 comprises a mounting shell 50, and two guiding holes 51 symmetrically formed in the mounting shell 50 at two opposite lateral sides. The holder frame 30 comprises a mounting structure.

According to this embodiment, one side of the walls 31 on the holder frame 30 comprises a gap 32 that is provided the signal cable 13 and power cable 14 through on it, and a mounting structure at the side of the gap 32. The mounting structure of the holder frame 30 is comprised of two posts 50′ that are internally threaded posts. Alternatively, embedded nuts may be provided to substitute for the posts 50′. Fastening members, for example, screws 52 are respectively inserted through the guiding holes 51 and threaded into the posts 50′ to affix the first electrical connector 10 to the holder frame 30. The first electrical connector 10 further comprises two guiding rods 16 symmetrically forwardly extending from the front wall of the mounting shall 50 at two opposite lateral sides for guiding the first connecting terminal 17 and the second connecting terminal 18 of the first electrical connector 10 into the first corresponding connecting terminal 21 and the second corresponding connecting terminal 22 of the second electrical connector 20.

Referring to FIG. 5 and FIG. 4 again, the first electrical connector 10 further comprises a first housing 11 and a second housing 12. The contact terminals 15 insert into the first housing 11. The second housing 12 covers a part of the first housing 11, a part of the signal cable 13 and a part of the power cable 14. The first housing 11 is manufactured first. Then, the contact terminal 15 are inserted into the first housing 11. The signal cable 13 and the power cable 14 are electrically coupled with the contact terminals 15. The second housing 12 is formed in a plastic injection process to protect the contact terminals 15, the signal cable 13 and the power cable 14. The second housing 12 not only keeping the terminals 15 well protected and electrically connected between the cables 13 and 14 and the terminal 17 and 18 but also provides a perfectly firm connection.

When in use, as shown in FIG. 6, the mounting shell 50 of the first electrical connector 10 is fixedly fastened to the posts 50′ of the holder frame 30, and then the holder frame 30 is fixedly fastened to the case 71 of the host system 70, keeping the signal cable 13 and the power cable 14 respectively connected to the signal connector 72 and power connector 73 of the host system 70. Further, the data storage device 60 is fixedly mounted inside a mobile rack 80. When the user inserted the mobile rack 80 into the holder frame 30, the second electrical connector 20 is forced into connection with the first electrical connector 10, and therefore the data storage device 60 is electrically connected to the host system 70.

As indicated above, the electrical connection interface of the present invention has the following features.

1. The first electrical connector 10 has a first connecting terminal 17 and a second connecting terminal 18 respectively connected to the signal connector 72 and power connector 73 of the host system 70 trough a signal cable 13 and a power cable 14 respectively for connecting the data storage device 60 to the host system 70 electrically without other interface requirement. Therefore, the connection of the data storage device 60 to the host system 70 is easy and trouble-free.

2. The first electrical connector 10 is directly electrically connected to the host system 70 through the signal cable 13 and power cable 14 thereof without through a circuit board. Because the invention eliminates the use of a circuit board, the invention saves much manufacturing cost and enhances data transmission stability.

A prototype of electrical connection interface has been constructed with the features of FIGS. 16. The electrical connection interface functions smoothly to provide all of the features discussed earlier.

Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
